A sharp smack with a mallet helps.

by Pedro, Verified Owner from GA, United States Written on November 6, 2025
I previously rated this product with two stars because of the difficulty folding it. I have since tried the advice of a internet poster suggesting a sharp whack with a mallet would break it loose. It did indeed. It folds and unfolds now quite nicely. That shouldn't have to be necessary.

Impossible to fold

by Pedro, Verified Owner from GA, United States Written on November 5, 2025
While this brace is sturdy, it's downright impossible to fold. I have researched the internet to try to find what I might be doing wrong and it appears to be a common issue. Many complaints center around the difficulty unfolding it but since I have yet to be able to fold it, I can't comment on unfolding it. I have seen one recommendation to hit it with a mallet to break it free. I'm not there yet.
Pros:
  • Sturdy
Cons:
  • Ridiculously tight mechanism
Best Used for:
  • A club
Would recommend: No

Excellent Folder

by thewong1, Verified Owner from TX, United States Written on September 15, 2025
The Sig folding brace is a very solid piece. There is no play/movement from the hinged point and the brace stays in position when locked. The pad will rotate around the frame but isn’t really an issue when using. I appreciate the fact that there’s not an excessive amount of strap on the pad, it makes for a cleaner look. Your’re going to need some effort tocollapse the brace for the first few dozen times, but it does get easier once you’ve got it broken in.
I’ve had no issues firing my Kuna with the brace folded, and it looks better than the Strike Industry that it originally came with.
Pros:
  • solid construction
Cons:
  • None
Best Used for:
  • AR carbines
Would recommend: Yes

Works like Expected

by Chris Bullock, Verified Owner from TN, United States Written on August 5, 2025
A little overpriced but hey all pistol braces are these days...but overall its fit and function is exactly what I expected it to be...mounts with the 1913 pic rail and has a lil button on the left side that has to be pushed for it to fold...I've only owned SB braces in the past so that was new to me but overall I love the look and it's made well it seems...also if it spins when you install it pop the black tab off the back of the brace and there will be a screw just tighten the screw out the tab back on and it wont spin as much
